All done, memory is (for now) at 2333mhz 10-12-11-28-2T 171 trfc (I still have to tune CR & tRFC). SA voltage is 1.176v (drooping from 1.19v) and VTT is 1.19v. DRAM voltage is still 1.65v, I'll try them at 1.7v after i've been to the hospital.
Will take it up to 2400mhz later today, this gskill memory is astonishing.
